Welcome to our blog!
We want you to be an informed homebuyer, and each blog post is a question that we have answered for our friends and customers over the years. Hope they help you make a good choice for your next home.

Here’s seven further requirements:

  1. 1)Receptacles serving countertop must have GFCI shock protection.

  2. 2)A receptacle is required for any wall behind counter space that 12-inches or more wide.

  3. 3)The space behind a sink or range does not count as countertop space if there is 12-inches or less behind it to the back wall.

  4. 4)Minimum of two 20-amp small appliance circuits serving refrigerator, all countertop and exposed wall receptacles in kitchen, dining room and pantry. Refrigerator can be on separate circuit.

  5. 5)Receptacles cannot be more than 20-inches above the countertop.

  6. 6)No receptacles allowed face-up on the countertop.

  7. 7)Minimum one receptacle for an island or peninsula countertop.

   Also, placing a receptacle directly behind a sink, like in the photo below, is not recommended because of the potential for the cord to fall into the sink.



While we hope you find this series of articles about home inspection helpful, they should not be considered an alternative to an actual home inspection by a local inspector. Also, construction standards vary in different parts of the country and it is possible that important issues related to your area may not be covered here.
